  1. Big 3 Comparison

    General Discussion
    I bought my 2008 KFX450 in excellent condition, low miles, and bone stock. I added an HMF slip on pipe, K&N intake, and an HMF optimzer. It sounds pretty good and in my opinion runs pretty good. I am pretty new to the sport and don't have much to compare it to. Apples to oranges, but I get...
  2. Sprocket Set UP

    General Discussion
    I have an 08 with full intake, HMF Optimizer, and an HMF slip on. I do a lot of wide open trail riding mixed with tight in the woods trail riding. Looking to see what the best set up is for the most speed all around. I want to keep up in tight trails and keep up/lead on straight aways...

  8. Chain/Sprocket Popping

    Engine/EFI/Drivetrain
    For some time now I've been getting a violent popping from my chain/sprocket. It only happens in heavy, rutted sand. Friends tell me that it is time for a new chain and/or sprocket.
